regmap: maple: free entry on mas_store_gfp() failure
[ Upstream commit f3f380ce6b3d5c9805c7e0b3d5bc28d9ec41e2e8 ]
regcache_maple_write() allocates a new block ('entry') to merge
adjacent ranges and then stores it with mas_store_gfp().
When mas_store_gfp() fails, the new 'entry' remains allocated and
is never freed, leaking memory.
Free 'entry' on the failure path; on success continue freeing the
replaced neighbor blocks ('lower', 'upper').
